The patch regulator: act8865: support output voltage by VSET2[] bits
has been applied to the regulator tree at git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From c86dc03e54ce15aac623125d92faac005f94267b Mon Sep 17 00:00:00 2001 From: Wenyou Yang <[email protected]> Date: Wed, 30 Sep 2015 15:25:49 +0800 Subject: [PATCH] regulator: act8865: support output voltage by VSET2[] bits For the step-down DC/DC regulators, the output voltage is selectable by setting VSEL pin that when VSEL is low, output voltage is programmed by VSET1[] bits, and when VSEL is high, output voltage is programmed by VSET2[] bits. The DT property "active-semi,vsel-high" is used to specify the VSEL pin at high on the board.
